COMBINATION CARPEN'IERS GAUGEV Application filed March 1, 1927; Serial No. 171,753.

My invention relates to new and useful improvements in a combination carpenters gauge, and has for its primary ob ect to provide in such a tool, a butt gauge that Wlll increase the accuracy of the work as laid out by the mechanic.

Another object of the invention is to provide a unique butt gauge marker, whereby either one of two points may be held inany adjusted position by a single set screw.

' A further object of the invention is to provide a rule adjustably mounted on the tool body which with the latter may be vused as a square.

A still further object of the invention is to provide an angle block for detachable connection with the tool body and cooperating with the rule so that the latter may be used as a triangle.

Another object of the invention is to provide a guidemember slidably mounted on the tool body and carrying a marker traveling along the line parallel with the outer edge of the rule for scribing a line at a distance from the rule parallel with its outer edge.

With these and other ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designatcd by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will portions broken away to'illustrate details of construction. 1 I

Fig. 2, is an enlarged perspective view of the sliding marker.

Fig. 3, is a fragmentary sectional view on the line 33 of Fig. 1.

Fig. 1-, is an enlarged perspective view of the butt gauge marker; and

Fig. 5, is a fragmentary perspectwe view of a piece of work on which the tool may be used when marking building trim.

In carrying out my invention as herein embodied, 10 represents the body of the tool or gauge having flanges 11 projecting from two opposite sides of the body at both ends thereof, so that in effect the body and its flanges form an H-shaped tool? Through the body longitudinally thereof, extends a hole 12 in which are mounted the semi-circular coacting butt gauge markers 13 and 14, each having at one end a barb or point 15, and when the two markers are in cooperative relation, as shown in Fig. 4, said points or barbs are at opposite ends. One of the markers, as 14, is provided with a longitudinal slot16 for registration with the shank of a set screw 17,which extends through a longitudinal slot 18 in the tool body, and has threaded connection with the other marker 13. From the foregoing, it will be noted that when the set screw is screwed home, it will bind 'uponthe tool body in the region of the slot 18 and draw the marker 13 toward the marker 14, and both of them toward one side of the hole 12, soas to clampboth the markers in any adjusted positionv relative to each other and to the tool body. hen it is desired to use the marker lgthe marker 13 must be sheathed within thetool body, thereby permitting said marker 1a to be withdrawn a distance equal to the length of its slot 16, and likewise, when it is desired to use the marker 13, the marker 1 1 is replaced, which will then permit the withdrawal of the marker 13.

In using either of the butt gauge markers they are witl'idrawn a distance equal to the i cut to be made, whichis indicated by the graduations 19, and then bymovingthe tool over anadjacent surface of the work, with one of the flanges in contact with such surface, a mark will be or barb 15.,

In one of the flanges, isa slot 20 for the reception of the rule 21 having one edge projecting asuitable distance beyond the outer face of such flange, andsaid rule is provided with a longitudinal groove 22 into which projects the hook 23 of the rod 2-1, the latter passing through a suitable opening in produced by the point 1 the flange, and then along the outside of the tool body, and then through a pair of spaced lugs 25, between which is mounted the thumb nut 26 having threaded engagement with the rod 24 so that after the rule has beenadjusted to any desired position, the turning.

,pf" the thumb nut 26 will bind the hook 23 into the rule, and thus hold said rule in the adjusted position. i

011 a flange adjacent the rule is mounted a slide 27, one face of which is parallel with the longitudinal edges of the rule and sub hrs 33.

stantially the salnedistance from the flange as the outer longedge ofthe rule, and said slide is held in any adjusted position by a set screw 28, passing through the slide and threaded into the flange on whieh the slide is mounted. This slide is prox ided with a longittuliiuil dovetail slot29 for thereception of the tongue 30 of the marker 31, which also includes a linger piece $2 and a sty- To use the last described portion of the invention which is particularly adapted for marking building trim prior to being sawed by the mechanics, a length not the trim 34: is laid in place with' one end fitting against the wall orother object, "Where it is to be fastened, While the other end overlaps a piece oi the door frame 35 or other object, as shown in Fig. 5. Then by placing the tool so that the loirer edge of the body rests upon the upper edgeot the trim and the outer edge of the rule against a. face of the object 35, the marker 31 IDHY bGITIOVG LlL up fancjl down so as to scribe a line on the, outer face of the trim 3% parallel with the face of the object goagainst which the rule is resting, so that-When the triin is sawed, it 'Will accurately fit against the object 35;

i In order to prorideifor angular work, an angle bloclt36 is reinovably mounted upon anedge of the tool body and is provided with an 211111 37 disposed on one side of the tool body with an aperture tor the passage of: a? set screw threaded into said body and said angle block has a slot 39 for registration with the rule 21. NVhen in use, the gauge may he placed against the Work to he niarkedwit-h the hypothenuse ot the angular block in (IOIllVilCt with one edge of the work through setting the outer edge of the rule at anangle tosaid edge.

Of course I do not wish to be liniited to the exact details or construction as herein and a marker slidahly mounted on the slide so as to parallel the outer edge 01: the rule.
